Dupont Delrin is the perfect plastic for turning on a lathe lathe. It is easy to turn, but it requires slow speeds. I have used this stuff to make Scottish small pipes chanters. I have purchased countless items from iPlastic. Smaller parts always ship promptly and everything has been well packed. I have never had a problem with an order.
Between the Delrin and Acetal rods, both materials are quite durable and easily machinable, and they have very similar physical properties. They look similar, but for practical uses there are some differences that can make one better than the other. It also depends on your application. As with all plastic materials, be sure to check the typical properties data sheet for the applicable properties you may need for your application.
Our Acetal Sheet is probably our primary material for machining,giving an nice finish both on manual and CNC Machines. Its got a pretty low moisture absorption making it the preferred grade for food contact and where the dimensional stability is important. Acetal Sheet has the best combination of high mechanical strength, durability and toughness, giving it outstanding sliding properties, electrical insulation, and wear resistance.
Acetal Sheet has countless uses and is certainly valued in the food preparation industry. Because of its low moisture absorption it helped it to achieve Food & Drug Administration approval in addition to its superb sliding abilities which aid with very low friction and hard wearing food safe components. Acetal Sheets are of the plastics used within the automotive industry because of its long term dimensional stability and toughness. It offers solutions for designers to help them create long lasting and very durable components. Another popular area for Sustarin C is in marine applications. This environment suits acetal well because the low moisture absorption will result in components that will not expand or change dimensions due to contact with water.
